Rangemaster Cortina Boost

I gave as a gift a bunch of Dallas Arbiter Rangemaster to some friends..
I branded them with a Cortina (famed, rich, skiing and lounging dolomitean village of the northern italian uppercrust) sticker.
Classic booster, classic location.

in one case, it was given as a (laugh) KIT!

My friend Enrico had it with a bigger value variable resistor (knob), so that he could dial it to fuzzy edges.
He said it is ‘too dirty’ for him (argh).
I called it STP-and badged it appropriately.
